Despite intensive research since more than 60 years, it is still unknown, whether neutrinos are their own antiparticles or not. This would have considerable implications for particle physics and cosmology. The neutrinoless double beta decay could provide the key information. The GERDA experiment is searching this hitherto still undetected decay for the germanium isotope 76Ge. Presently, GERDA is world leading with the strongest suppression of background events and the best energy resolution, thus providing excellent conditions for a future discovery of the decay.
